You often see old cordless phones tossed out on junk day or at fleamarkets for a few cents.
Can the antennas on these be used for wifi projects?
What dBi would they be (handpiece v's the basestation).
Just thinkin :-)

Yep. The battery dies, so the owner just throws away the whole cordless phone instead of buying a replacement.
No. The lack of a proper RP-SMA or RP-TNC is the major problem. If you disassemble the cordless phone, what you'll probably find is a
1/4 wave piece of wire inside a rubber or plastic antenna "radome". 1/4 wave at 2.4GHz is about 3.125". The antenna can be approximately this length, or twisted into a spring shape. 1/4 wave, under ideal circumstances is about 0dBi. If the antenna looks like a spring and is (for example) half the 1/4 wave length, then the gain is -3dBi.You'll do better to make your own directional antenna from scratch.
